tweak(win): re-introduce the >=1920px IDE bar-height trim (owner-approved)

Lifts the "freeze nBarH" lock added in 7579053. The main IDE bar is
trimmed by 70px on screens >= 1920px wide (nBarH -= 70); smaller
resolutions keep the full Max(200, Int(200*nUIScale)) height.

The DO-NOT-CHANGE banner above the nBarH line is replaced with a short
history note; ChangeLog's "DECISION (locked)" entry is updated to
"DECISION (reversed)". Trade-off (slightly clipped palette button row on
big screens vs. avoiding the documented ~6-9s self-exit) acknowledged
and accepted by the owner.

bin/hbbuilder_win.exe rebuilt (MSVC x64).

-  - DECISION (locked): the main IDE bar height (nBarH in Main()) is now
-    FROZEN at its full computed value, Max(200, Int(200*nUIScale)). The
-    per-screen "nBarH -= 60/70" trim has been removed and must NOT be
-    re-added under any circumstances — there is a matching DO-NOT-CHANGE
-    banner above the line in source/hbbuilder_win.prg. Rationale: the
-    project owner chose a visible component-palette button row over the
-    bar-trim, in full knowledge that the full-height bar coexists with
-    the self-exit issue described in the previous note. If someone
-    genuinely fixes that self-exit, fix it on the C++/layout side, not
-    by touching this line, and ask first.
+  - DECISION (reversed): the earlier "freeze nBarH at full height" lock
+    has been lifted at the project owner's request. The per-screen trim
+    is back: nBarH -= 70 when nScreenW >= 1920 (smaller screens keep the
+    full Max(200, Int(200*nUIScale)) height). The DO-NOT-CHANGE banner in
+    source/hbbuilder_win.prg has been replaced with a short history note.
+    Trade-off acknowledged: on >=1920px screens the trimmed bar drops the
+    bottom of the component-palette button row slightly, but it also
+    avoids the self-exit described in the note below; the owner judged
+    that the better deal.
